Report Abuse. The collision of an oceanic plate, and a continental plate produce a plate boundary known as a subduction zone. The colder, denser [typically basaltic crust (approx. 3.3g/cm^3)] oceanic plate is forced underneath the less dense [typically granitic (d= 2.7)] continental crust.
Oceanâcontinent convergence occurs when oceanic crust is subducted under continental crust. This forms an active continental margin between the subduction zone and the edge of the continent. The leading edge of the continental plate is usually studded with steep andesitic mountain ranges.
